What a Currency ?

I don't know what is your currency, but since I was born until today nobody tell me why 'Rupiah' choosed to be Indonesian currency and why the zero become long each decade? Nobody knows.
When I was 3 years old, Rp. 25 can used to buy a lollypop but now, even jobless don't want to accept it. No value at all.
This picture looks so nice, if it's in US Dollar currency. You know? it's only $ 10. Lot of zero doesn't mean has big value. Economics! Everyone Loves It.
